I can decode the raw VC-1 streams. All the required information is present.

Here's a dump of the sequence header for asasadad_1's stream:

SeqHeader: 1

+->FRMRTQ_POSTPROC: 7 (30 frm/s)
+->BITRTQ_POSTPROC: 31 (2016 kbps)
+->POSTPROCFLAG: 0 (FALSE)
+->MAX_CODED_WIDTH: 959 (1920)
+->MAX_CODED_HEIGHT: 539 (1080)
